The GA Killer was an assassin of the Key War, an aardvark, whose name remains unknown. The GA Killer first surfaced in 405 AB. In this year, several leading generals of the Great Army were killed with the letters GA written onto their backs. The Afrotherian Anarchy government allowed this to continue, and security was raised on all fronts by the Great Army. Despite this, in early 406 AB several other generals were killed, and the commander of the Great Army, Hurm Porrg, resigned his command and sailed north. The new commander, Brac Hoo, was killed in broad daylight; he was making a speech before the army on how they need not fear the GA killer and on how the Perissodactyls were cowards for doing so (Hurm Porrg was a Plains Zebra) when he was shot with several poisoned arrows by an aardvark
